Aluminium and uPVC systems hold very good thermal and sound insulating qualities, with trickle ventilation and controlled drainage. They are sufficiently strong and stable to standards. The aluminium profiles are constructive healthier and practically eternal. Most often the life of uPVC is less, depending on the conditions and maintenance. As talk about price, aluminium systems are significantly more expensive than uPVC, so if we talk about the relationship price-quality uPVC systems come to the fore. The profiles you choose depend on your home and your personal taste.
